Proceeding from the thought of blasted fragments having the fractal characteristics, the calculation of blasted fragment sizes was related to the mechanism of blasting in jointed rock masses by the new concept of "rock mass fracture ratio" presented and , thus, the model of damage mechanics for blasting in rock masses was established, which reflects the blasting essence of both rock masses breaking along joint planes and rock breaking.

从爆破岩块具有分形特征的思想出发，通过提出&岩体破裂比率&概念，将爆破块度计算同节理岩体爆破机制相联系，建立起岩体爆破块度的损伤力学模型，该模型反映了岩体沿节理面破裂和岩石本身破裂的岩体爆破本质。

In the process of impact of abrasive jet on rock, resulting dynamic stress plays an important role in rock destruction. The stress wave resulted makes local rock tensile and shearing, then makes rock destructed. In the conditions of some hypotheses, the mechanical model that rock is applied by stress wave, i.e. jet wave basic equations, are set up by wave theory, and the formula of the maximum normal stress resulted by stress wave is deduced according to known boundary conditions.

描述了岩石材料在磨料射流的冲击下破坏的主要原因，分析了应力波就是岩石局部受到拉伸和剪切并最终使岩石发生破坏的根本因素，在这一假设的前提下采用波动理论建立了岩石受应力波作用的力学模型即射流波动的基本方程，在已知的边界条件下推导出了由波动引起的最大正应力的计算公式。

首先，建立了主溜井三维有限元计算模型，模拟了主溜井围岩的塌落破坏过程和加固后的加固体的稳定性及变形特性；同时，还采用多点位移计等对加固体的稳定性进行了实地监测。计算结果表明：网棚锚注加固体的纵剖面上的压力和位移规律是①加固体下部局部出现拉应力区，表明锚杆的使用是合理的；②加固体内的应力由塌落中心向周围围岩过渡，应力越来越大，最终将荷载传至围岩中；③从下到上下沉逐渐减小；④从加固体中心到周围下沉位移逐渐减小，且近似一条抛物线。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
